LPC1110/11/12/13/14/15

32-bit ARM Cortex-M0 microcontroller

Functional description

7.1 ARM Cortex-M0 processor

The ARM Cortex-M0 is a general purpose, 32-bit microprocessor, which offers high

performance and very low power consumption.

7.2 On-chip flash program memory

The LPC1110/11/12/13/14/15 contain 64 kB (LPC1115), 56 kB (LPC1114/333), 48 kB

(LPC1114/323), 32 kB (LPC1114), 24 kB (LPC1113), 16 kB (LPC1112), 8 kB (LPC1111) or

4 kB (LPC1110) of on-chip flash memory.

7.3 On-chip SRAM

The LPC1110/11/12/13/14/15 contain a total of 8 kB, 4 kB, 2 kB, or 1 kB on-chip static

RAM memory.

7.4 Memory map

The LPC1110/11/12/13/14/15 incorporate several distinct memory regions, shown in the

following figures. Figure 14 shows the overall map of the entire address space from the

user program viewpoint following reset. The interrupt vector area supports address

remapping.

The AHB peripheral area is 2 MB in size, and is divided to allow for up to 128 peripherals.

The APB peripheral area is 512 kB in size and is divided to allow for up to 32 peripherals.

Each peripheral of either type is allocated 16 kB of space. This allows simplifying the

address decoding for each peripheral.
